IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No.142,305, dated August26, 1873; application filed June 2, 1873.

- ings, of which Figure 1 is a vertical section, and Fig. 2 a horizontalsection, of a Window provided with my invention. Fig. 3 is a side view,Fig. 4 a top view, and Fig. 5 an edge view, of one of thesashsupporters.

Each sash, A or B, is grooved vertically on 'one or each of its outeredges, as seen at a, to

receive one of the supporters 0, which consists of a strip of vulcanizedIndia rubber, b, and two strips, 0 c, of wood or other inelastic orstiff material, rabbeted,fastened together, and arranged asrepresented-that is to say, the elastic strip bis wider than each of therabbeted flanking-strips cand they are placed on opposite sides of thestrip b, and disposed so that it may at its outer edge project a shortdistance beyond them, and also at its inner edge a longer distancebeyond them, all as shown, the part f so projecting, when the supporteris in the sash, serving as a spring to force the outer edge of therubber stripin contact with the next adjacent edge or part g of thewindow-frame D.

From the above it will be seen that the clastic strip of rubber not onlyserves as a spring to press the supporter against the sash andwindow-frame, but as a friction-brake to arrest the sash or hold it upat an elevation within the range of its movement in the window-frame.

Theflanking-strips of the supporter not only operate to sustain theelastic strip of rubber, but to enable the supporter to slide freelyhorizontally in the sash-groove, the said flanking, strips beingfastened together and to the elastic strip by rivets or other suitablemeans.

I am aware that it is not new to apply to a sash a friction-bar, and oneor more springs to force such bar against the window-frame. Therefore, Imake no claim thereto. I am also aware that it is not new to use Indiarubber within a sash for supporting it in its frame, and, therefore,make no claim to such in the abstract. In my supporter each of theflanking-strips is rabbet-ed lengthwise, inorder to form between them achamber or space for the elastic strip to expand in. These rabbetedstrips, therefore, become important features of my invention. a

What I claim as new, and desire to secure by Letters Patent, is

The sash-supporter 0, consisting of the clastic strip b and the tworabbeted flankingstrips 0 a, forming a single piece, the elasticsubstance projecting on either side, loosely fitting in lengthwise ofthe sash, all substantially as described and shown, for the purpose setforth.

JOSEPH WARE.
